1. Before pottery wheel installation should check to see whether there are cracks, and hit the wheel with a wooden hammer, whether there were unusual to hear hoarse voice, if there is, the wheel can not be used to avoid wheel breakage caused wounding consequences.
2. The newly installed or every other day using the wheel, you should re-use idle more than a minute, if all goes well, you can use the diamond grinding cup machine in accordance with the relevant safety procedures.
3. Since the ceramic wheel brittle and fragile, please do not let by the impact, collision, not fall. When stored frost, moisture, keeping cool indoor ventilation, place the flat, stacked neatly against dust, remains unused wheel clean, not stress.
4. Ceramic wheel installation, you must look for positive wheel center, and should the tightening flange mounted on the flange should be examined later whether the spindle concentric cylindrical stone cutting wheel, grinding wheel having at least one side of the vertical centerline of the spindle.
5. After the installation of ceramic grinding wheels, for safety reasons, do not properly qualified protective enclosure will be installed, and then start the machine use.

How to choose the wheel?
Abrasive wheel is a grinding tool indispensable, select the appropriate wheel or not, affect the quality of grinding, the grinding cost important condition. The company produces a range of surface grinders, the wheel must be configured to accommodate different plane processing various workpiece. For the convenience of the user and the company design, technology choices, which this paper plane grinding, grinding wheel used different workpiece material selection summary for everyone to use reference.
Many different types of stainless steel cutting wheel, and a variety of shapes and sizes, due to the different abrasive grinding wheel, grinding wheels binder material and manufacturing process, the wheel would have a variety of different performance. Each tile cutting wheel in accordance with its own characteristics, there is a certain scope. Therefore, grinding, must be based on the specific circumstances (such as the material properties of the workpiece grinding, heat treatment method, the workpiece shape, size and processing forms and technical requirements, etc.), choose the appropriate wheel. Otherwise it will directly affect the inappropriate choice of wheel machining accuracy, surface roughness and productivity.

Cut off wheels
LEMAN concrete cutting wheels is usually cut with water (wet cutting), for concrete cutting wheels with adequate water can significantly reduce the dust, keep construction cutting blades cool and extend its life, and improve the cutting efficiency (for wet cutting can be deep and continuous).
However, when there is no water source near the work area, you have to perform dry cutting. As said in the previous section, dry stainless steel cutting wheel should be intermittent and shallow. If deep cutting depth is needed, you should do several passes of shallow cuttings.

Concrete cutting disc
Often the decision of stainless steel cutting wheels wet or dry depends on your preference and job requirements. Dry cutting eliminates messy wet slurry and the need to equip saws with water tanks and hoses. Using a blade wet, on the other hand, reduces dust but makes it necessary to contain or clean up the slurry. For indoor jobs where you need to keep the work area dry, a dry-cutting blade and compatible saw may be your only option.
The main difference between wet and Tile cutting discs is the weld (as described in Step 1). Dry-cutting blades have segment welds that resist heat and don't require water for cooling. They are usually intended for intermittent cutting and for use on handheld, low-horsepower saws. If you're sawing decorative pattern lines in concrete, dry-cutting blades are often the best choice for making crisp, clean cuts (see Sawing and Patterning). These decorative cuts are typically only 1/16 to 1/4 inch deep and do not function as control joints.
Wet-cutting blades are typically used with walk-behind saws for cutting joints in cured concrete flatwork because water cooling permits deeper cuts. Although it's possible to use most abrasive factory with water, never use a wet-cutting blade dry. Always continuously cool the blade with water to avoid segment loss and blade warpage.

Construction cutting blades
For maximum cutting speed and blade life, you should match the blade as closely as possible to the material you're cutting. Characteristics of the concrete you need to know include the compressive strength, the size and hardness of the aggregate, and the type of sand.
Blade manufacturers consider concrete with a compressive strength of 3000 psi or lower a soft material and Diamond cutting discs with a strength above 6000 psi a hard material. Therefore, you should use a blade with a hard bond to cut the lower-strength concrete and a blade with a soft bond to cut high-psi concrete. Similarly, hard aggregate (such as trap rock, basalt, and quartz) dulls diamond particles quickly, so use a blade with a softer bond to allow new diamonds to be exposed as needed.
The size of the aggregate in concrete primarily affects blade performance. When cutting through larger aggregate (3/4 inch and up), construction cutting discs and wears more slowly. Pea gravel (smaller than 3/8 inch) is easier to cut, but the blade will wear faster.
The type of sand determines the abrasiveness of concrete, with sharp sand being the most abrasive cutting wheel and round sand the least. To determine the sharpness of the sand, you need to know where it's from. Crushed or river bank sand is usually sharp while river sand is round and nonabrasive. The more abrasive the sand, the harder the bond requirement.
What if you will be cutting more than one type of concrete? As a general rule, manufacturers recommend choosing the blade based on the material you'll be working with most often or the material for which top blade performance is most important. Most diamond blades can cut a range of materials.

Concrete cutting discs
Concrete can also be cut with abrasive blades, but diamond blades are recommended, for cutting blades can provide at least two times faster cutting, less downtime, and constant depth of cuts.
If you use the diamond blades occasionally and your jobs are small, you can choose the economical grade diamond construction to save your expense (but the cutting speed of the economical diamond blades should be fast enough). If you use the diamond blades frequently or the job is big, you should choose high grade professional diamond blades, for this can decrease your cost per cut.
If you are not sure that you can do concrete cutting wheels job well, you can just hire a professional concrete cutting company to do the job for you.

Diamond discs
You should at least wear a professional respirator, not only in dry cutting, but also in wet cutting, because the small dust particles generated in metal cut off wheels process can penetrate deep into the lungs and can cause serious health effects such as lung cancer or silicosis. If the job is big, other equipment like goggle, earplugs, and protective clothing should also be adopted.
To make the cut straight, you can use a chalk line to mark a straight line on diamond blade, and then place a straight wood board along the line. Then you can cut a shallow line on the concrete along the wood board. The cut can be about 1/4″ deep.Having this shallow straight metal cutting discs, you can perform further cuttings along it to gain the cut you need.

Til granite cutting wheels
What type of handheld saw or flat saw are you using? What is the horsepower and operating speed (or rpm)? Blade manufacturers provide charts with recommended operating speeds and maximum safe operating speeds for their blades. You'll also find this information stamped right on the multi use diamond disc.
Always match the blade with the speed range of the saw. Operating the blade at a lower speed than recommended can concrete cutting blades its cutting life and performance. Exceeding the blade's maximum rpm rating can damage the blade and risk injury to the saw operator.
Other factors to consider:
Blades designed for wet use only must be operated by saws that can deliver a continuous supply of water to cool the blade.Most blades for cutting green concrete are designed for use with special early-entry saws that minimize joint raveling and spalling.Don't use a blade that exceeds the maximum blade diameter and tile cutting wheels depth capacity of the saw.
